PROBLEM TO BE SOLVED: To provide an organic EL material which achieves a longer service life.SOLUTION: An amine derivative having a fluorine-substituted aryl group is represented by formula (1). [In the formula (1), Ar1 and Ar2 are each independently a substituted or unsubstituted C6-C14 aryl group or the like; L is a substituted or unsubstituted C4-C14 arylene group or the like; R1 and R2 are each independently a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heteroaryl group; a is an integer satisfying 0≤a≤3; and at least one of Ar1 and Ar2 is substituted with at least one fluorine atom.] |
